M.B.
I like what someone once posted about when their child kept saying "I was just kidding.. I was just joking" in response to different things....
Basically, the parent talked about going and doing something special after dinner, like getting ice cream.. something the child was really wanting.... when the time came to go out, and the child was really anticipating the treat, the parent said... "Oh, sorry.. I was just joking... we're not going anywhere".
The child got the message....
